Description

The false stargazer is a stargazer (Uranoscopidae) from the deep, cool waters of the southern hemisphere. The species has a stocky body with a large, upward-directed mouth and eyes on top of the flattened head, characteristic of stargazers that bury themselves and peer upward. It lives bottom-dwelling and is usually caught with trawls at 200 to 800 m depth. As an ambush hunter it springs on passing fishes and crustaceans. Like other stargazers it bears venomous shoulder spines; a sting is painful.
